Porsche has unveiled a lightly updated version of its compact SUV, the Macan. The exterior sees a number of subtle changes including LED headlights, new 20- and 21-inch wheels and a revised light strip across the rear. There are also four new colour options. Inside, the Macan gets an 11-inch infotainment touchscreen, redesigned air vents and the GT steering wheel from the 911. Other options include a heated windscreen and an ioniser to improve air quality.
